What is AWS Lambda?

AWS Lambda is a compute service that lets you run code without provisioning or managing servers. AWS Lambda executes your code only when needed and scales automatically, from a few requests per day to thousands per second. You pay only for the compute time you consume - there is no charge when your code is not running. With AWS Lambda, you can run code for virtually any type of application or backend service - all with zero administration. AWS Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, code monitoring and logging. All you need to do is supply your code in one of the languages that AWS Lambda supports (currently Node.js, Java, C# and Python).

We use AWS Lambda because it provides a solution for our needs without requiring us to manage our infrastructure. With the tool, we only pay for the resources we use. Additionally, it is straightforward to implement and integrates with other services like API Gateway. The tool's serverless nature has had the most significant impact on our workflow. I find it particularly attractive because it eliminates the need for managing servers. In my previous experience, managing upgrades and updates was quite challenging. The solution's integration process with other AWS services was relatively easy. We primarily use AWS services such as EventBridge for scheduling processes and log management.

It has access to various other AWS resources like S3. You can use it to configure event-based triggers or conditions. You don't need to configure the servers; it will automatically execute the job and go idle. In that regard, Lambda is good and serves the purpose. Integration capabilities: They have the built-in IDE, so everything happens without integration issues. AI-features: Just the Amazon Q [Amazon Simple Queue Service (SQS)] will also be there, like a pop-up in the AWS console. We can use that for Lambda as well, but no other integration. I wish there were AI integration for the code, like CodeWhisperer. That would be a good add-on.

One area where AWS Lambda could be improved is the execution timeout limit, which is currently capped at 15 minutes. This is restrictive for tasks that require longer processing times, such as complex data analysis or large-scale batch processing. Additionally, the environment customization is limited, particularly with regard to file system access, persistent storage, and certain execution capabilities, which can be restrictive for more advanced use cases. Another area for improvement is the cold start latency, which can add significant overhead to the execution time, especially for applications with infrequent or unpredictable invocations. For future releases, it would be helpful if AWS Lambda allowed for longer execution times or offered an option for more flexible execution environments. Reducing cold start latency or offering features like provisioned concurrency with more granular control could also help improve the overall performance and responsiveness of Lambda functions.

Valuable Features

"Lambda is trigger-based, which means it only activates when accessed, ensuring cost savings."
"AWS Lambda is cost-effective, providing noticeable cost savings."
"AWS Lambda's event-driven architecture is highly valuable."

Room for Improvement

"AWS Lambda is a bit difficult to set up if someone doesn't know how to code."
"I would like to see improvements in AWS Lambda's stability and setup processes, as there were some complexities encountered initially."
"AWS Lambda has a maximum execution timeout of 15 minutes, which is unsuitable for long-running tasks."

Pricing

"AWS Lambda is not expensive for micro testing but is expensive if used for long deployment or long services."
"The solution is free of cost for the first year, and after that, it becomes expensive."
"It costs maybe less than $10 per month in my use case."

Learn more about AWS Lambda

You can use AWS Lambda to run your code in response to events, such as changes to data in an Amazon S3 bucket or an Amazon DynamoDB table; to run your code in response to HTTP requests using Amazon API Gateway; or invoke your code using API calls made using AWS SDKs. With these capabilities, you can use Lambda to easily build data processing triggers for AWS services like Amazon S3 and Amazon DynamoDB process streaming data stored in Amazon Kinesis, or create your own back end that operates at AWS scale, performance, and security.
